Benefits of technology

"The present invention is a character recognition processing device that improves the rate and accuracy of recognizing characters. It uses a cursor position information system to analyze the arrangement of characters and extract the character image for recognition. This eliminates the need for a high-spec device and reduces the cost and power consumption of the device. Additionally, the device can extract the character image from multiple frames of a continuous photographing operation, further improving the accuracy of recognition. The device can be used in a portable terminal device, making it convenient for users to capture and recognize characters."

Problems solved by technology

Thus, a host CPU or a MIPS (Million Instructions Per Second) value of a DSP or a work RAM undesirably needs to be increased.

first embodiment

[0065]FIG. 1 is a block diagram showing the structure of a portable terminal device having a character recognition processing device according to a first embodiment of the present invention. In this embodiment, a structural example that the character recognition processing device 2 is mounted on the portable terminal device 1 is described.

[0066]The character recognition processing device 2 of this embodiment includes an image fetching part 3, a cursor control part 4, a layout analyzing part 5, a character cutting part 6, a character recognizing part 7 and a format output part 8. These component elements are realized by the operation of a software program, the combination of software and hardware or an exclusive hardware in a control processing part including a processor and a memory or the like.

[0067]The portable terminal device 1 includes a photographing part 9 composed of, for instance, a CCD camera, a display control part 10 and an application part 11 in addition to the character...

second embodiment

[0073]Now, an operation of a character recognition processing device according to a second embodiment of the present invention will be described by referring to FIGS. 3 and 4. FIGS. 3 and 4 are explanatory views of an operation during a character recognizing process according to the second embodiment. FIG. 3 shows a state that a character string as an object to be recognized is photographed. FIG. 4 shows a manner of the character recognizing process relative to the character string as the object to be recognized that is divided into a plurality of parts. Since the structure of the character recognition processing device is the same as that of the first embodiment, FIG. 1 is applied thereto.

[0074]In the second embodiment, a character string 23 as an object to be recognized in an object 22 whose character is to be recognized is photographed by a photographing part 9 of a portable terminal device 1 to recognize a character in the same manner as that of the first embodiment. In this cas...

third embodiment

[0084]Now, one example of a structure and an operation when a character recognition processing device is mounted on a portable telephone as a third embodiment will be described below.

[0085]FIG. 5 is a view showing the structure of an external appearance of a portable telephone according to the third embodiment of the present invention. FIG. 5(A) is a front view and FIG. 5(B) is a rear view. The portable telephone 30 of this embodiment includes a first casing 31 and a second casing 32. On a front surface side of the first casing 31, that is, on a surface that mainly faces a user when the user opens the first casing 31 and the second casing 32 and holds them, a first display part 33 composed of a liquid crystal display element is provided. Further, in a rear surface side opposite to the front surface of the first casing 31, a camera 34 as a photographing part and a second display part 35 composed of a liquid crystal display element are provided.

[0086]On the front surface side of the s...

Abstract

It is an object of the present invention to improve a rate of recognition and recognition speed, reduce a degree of a specification required for a device forming a photographing device or a system and lower consumed electric power and a cost. In a character recognition processing method according to the present invention, a character image as an object whose character is to be recognized is displayed on a display (12) together with a cursor of a character frame for recognizing a character. While the cursor is set to a character string as an object to be recognized, the character image is photographed by a photographing part (9). In an image fetching part (3), the image data of the photographed character image is fetched. In a layout analyzing part (5), the fetched image data of the character image and cursor position information from a cursor control part (4) corresponding to the character image are received. The image data is collated with the cursor position information to analyze the arrangement of the lines or characters of the character string as the object to be recognized. Then, in a character cutting part (6), the character is cut on the basis of the analyzed result. The character is recognized relative to the character image by a character recognizing part (7) to convert the image data to character data.

Description

TECHNICAL FIELD[0001]The present invention relates to a character recognition processing device, a character recognition processing method and a portable terminal device that are preferably used for a portable terminal device such as a portable telephone, a portable information terminal or the like.BACKGROUND ART[0002]As a usual character recognizing method and a usual character recognizing device, a character recognizing method and a character recognizing device that are disclosed in, for instance, JP-A-2001-60250 (Patent document 1) and JP-A-2000-76378 (Patent document 2) have been known.[0003]In the character recognizing method and the character recognizing device disclosed in JP-A-2001-60250, a feature amount is extracted from a character whose image is inputted and the character is recognized on the basis of the extracted feature amount. In this example, every time the character whose image is inputted is scanned at prescribed intervals, the number of times of the intersections...
